Supersonic Free-Jet Combustion in a Ramjet Burner

WebWhen something goes through the air at a speed above Mach 5, it becomes hypersonic, and is known as a ‘scramjet’ (a supersonic combustion ramjet). There are already hypersonic missiles travelling through the air at incredible speeds, and which are controllable and directable mid-flight in a way that far outdoes intercontinental ballistic missiles (ICBMs). Web2 mag 2011 · This is a design that operates as a ramjet system at lower supersonic Mach numbers with subsonic combustion and as a scramjet system at higher Mach numbers with supersonic combustion. In the ramjet system the isolator, the duct between the inlet and the combustion chamber, will contain a series of shocks known as a shock train. golf mart india https://bijouteriederoy.com
